Earlier today, Google has announced a developer preview of WebM, which is essentially an open source media format, designed for World Wide Web, that uses VP8 codec.

In response to such announcement, Microsoft’s Internet Explorer General Manager, Dean Hachamovitch said: “In its HTML5 support, IE9 will support playback of H.264 video as well as VP8 video when the user has installed a VP8 codec on Windows” … “We want to be clear about our intent to support the same markup in the open and interoperable web, and to do so in a manner consistent with our view broad view of safety and security”

The WebM is already supported by 40+ companies, such as: Mozilla, Opera, Google, Logitech and many more.
